well ok, stll dartcraft dont balanced with iguana tweaks for tcronstruct (i will call it ITFTC ok) on my opinion, but it an personal opinion, so yea.
im do my own pack that really close to your, (i didnt copy, i made it 3 weeks ago, for myself, and now i decided to share it)
it lighter pack (27 mods now, but it growing. instead 56), without all the mods that make their own tools and armor (beside the metallurgy, that i want to disable all their own tools that dont making on the smeltery, and magical crops, that make what i want as "end game" armor so he can to survive the enderpocalypse and the alien invension that i want to add later, i want to change the recipe for the infused diamond, with manyullyn instead diamonds, and infused stone by steel instead of emerald/diamond).
you can try it out and say what are you think
